      spi: conditional checking of mode and transfer bits. · db90a441
      Sourav Poddar authored
      There is a bug in the following patch:
      http://comments.gmane.org/gmane.linux.kernel.spi.devel/14420
      
      spi: DUAL and QUAD support
      
          fix the previous patch some mistake below:
          1. DT in slave node, use "spi-tx-nbits = <1/2/4>" in place of using
             "spi-tx-dual, spi-tx-quad" directly, same to rx. So correct the
             previous way to get the property in @of_register_spi_devices().
          2. Change the value of transfer bit macro(SPI_NBITS_SINGLE, SPI_NBITS_DUAL
             SPI_NBITS_QUAD) to 0x01, 0x02 and 0x04 to match the actual wires.
          3. Add the following check
             (1)keep the tx_nbits and rx_nbits in spi_transfer is not beyond the
                single, dual and quad.
             (2)keep tx_nbits and rx_nbits are contained by @spi_device->mode
                example: if @spi_device->mode = DUAL, then tx/rx_nbits can not be set
                         to QUAD(SPI_NBITS_QUAD)
             (3)if "@spi_device->mode & SPI_3WIRE", then tx/rx_nbits should be in
                single(SPI_NBITS_SINGLE)
      
      Checking of the tx/rx transfer bits and mode bits should be done conditionally
      based on type of buffer filled else EINVAL condition will
      always get hit either for rx or tx.

      spi/qspi: Add qspi flash controller · 505a1495
      Sourav Poddar authored
      The patch add basic support for the quad spi controller.
      
      QSPI is a kind of spi module that allows single,
      dual and quad read access to external spi devices. The module
      has a memory mapped interface which provide direct interface
      for accessing data form external spi devices.
      
      The patch will configure controller clocks, device control
      register and for defining low level transfer apis which
      will be used by the spi framework to transfer data to
      the slave spi device(flash in this case).
      
      Test details:
      -------------
      Tested this on dra7 board.
      Test1: Ran mtd_stesstest for 40000 iterations.
         - All iterations went through without failure.
      Test2: Use mtd utilities:
        - flash_erase to erase the flash device
        - mtd_debug read to read data back.
        - mtd_debug write to write to the data flash.
       diff between the write and read data shows zero.

      spi: limit default transfer speed to controller's max speed · 56ede94a
      Gabor Juhos authored
      Since the 'spi: Support transfer speed checking in the core'
      change, the SPI core validates the desired speed of a given
      transfer against the minimum and maximum speeds supported by
      the controller.
      
      If the speed of a transfer is not specified, the core uses
      the maximum speed of the actual SPI device. However if the
      maximum speed of the actual device is greater than the
      maximum speed of the controller, the core will reject the
      transfer due to the aforementioned change.
      
      Change the code to use the maximum speed of the controller
      by default if that is below the device's maximum speed.

      Pull qxl drm fixes from Dave Airlie:
       "Okay as I warned, the qxl driver was running a bit free and loose with
        its ttm object reservations and the new lockdep enabled reservation
        tracking shone a bright light into it, it also with the new
        reservations mutexes hits a possible deadlock during boot.
      
        The first patch is a real fix to render the console correctly as the
        driver used to just drop irq renderering as too hard, this also fixes
        a sleeping while atomic warning.
      
        The other two patches are the big ugly ones that redo how the driver
        allocates objects and reserves them and makes things all work
        properly, I've tested this in a VM, and compared to the current code
        which hits a lockdep warning and the sleep while atomic warning before
        failing.
      
        So sorry this is coming in late, I should have tested qxl before
        merging the mutex code, but I'd rather just fix qxl with this than
        revert the reservations code at this point"
